In this paper we study the H+γ (H=J/Ψ and ϒ) production in coherent hadron–hadron interactions at LHC energies. Considering the ultrarelativistic protons as a source of photons, we estimate the γ+pH+γ+X cross section using the non-relativistic QCD (NRQCD) factorization formalism and considering different sets of values for the matrix elements. Our results for the total p+pp+H+γ+X cross sections and rapidity distributions at \(\sqrt{s} = 7\ \mbox{and}\ 14\ \mbox{TeV}\) demonstrate that the experimental analysis of the J/Ψ+γ production at LHC is feasible.
